I downloaded the Mastercam Licensing Utilities to generate the linking code for Mastercam U. I have a login for Mastercam.com, but trying to run mastercamdotcomlinking but it doesn't work. It says my firewall or antivirus is blocking it, or mastercam security device is currently disabled or unplugged. Mastercam HLE 2021 installed on home PC, windows 10, I tried turning off firewall and antivirus (just windows defender basic) to try it again but that didn't work. Has anyone had this issue?

Did you get any help with this? I'm running into a similar problem with the mill essentials ebook not opening when I try to log in it just doesn't want to open. Can't figure out how to email customer support either?
